Lard, candles and soap
economicstrade & commercializationhistory
Claim: the fat of the pig built one of America's biggest companies. Evidence: lard was the main cooking and baking fat for most families, and packing-house fat also went into candles and soap. In 1837 a Cincinnati candle maker, William Procter, and a soap maker, James Gamble, joined to found Procter & Gamble, using fat from "Porkopolis"; in 1911 the same company launched Crisco, a vegetable shortening that began lard's long decline.
Ask: why did a meat city become a soap city? Trace one by-product from the pig to a store shelf.
